Floor furnace



Oct. 5, 1943. G,v A KUMLER FLOOR FURNACE Filed July l2, 1940 Patented Oct. tu', 1943 FLOOR FURNACE George A. Kumler, Los Angeles, Calif., assignor to Oil Devices, Santa Fe, N. Mex., a limited partnership of Illinois Application July 12, 1940, Serial No. 345,133 3 Claims. (Cl. 126-116) My invention relates to an improvement in securing or positioning means for positioning pots of pot type burners.

One purpose is the provision of means for giving ready' access to pot type burners when used in connection with floor furnaces.

'fAnother purpose is the provision of readily detachable securing means for such pots for pot type burners, adapted to permit their ready removal from furnaces or burner units. such for example as oor furnaces,

Other purposes will appear from time to time in the course of the speciilcation and claims.

I illustrate my invention more or less diagram, matically in the accompanying drawing wherein:

Fig. 1 is a vertical axial section;

Fig. 2 is a section on'the line 2-'2 of Fig. yl;

Fig. 3 is a section on the line 3--3 of Fig. 1;

Fig. 4 is a variant form of a portion of my device; and

Fig. 5 is another variant form of a portion of my device.

Like parts are indicated by like symbols throughout the specification and drawing.

Referring to the drawing, I generally indicates a floor furnace housing, which may be of any suitable form, but which is herein shown as generally rectangular in cross section. Its upper end may be closed for example by a floor grille or the like, indicated at 2. 3 indicates 'an inside sleeve, herein shown as cylindrical, and mounted on the housing I lby means of any suitabley brackets or connectors 4. 5 is an inner burner drum, herein shown as cylindrical in form, and having a top 5a. It. may be mounted upon the sleeve 3 by means for example of connecting brackets or the like 5b. It Ais pro ided with an outlet flue 6, one snide thereof tending outwardly through the drum 3 and the housing I, as shown for example in Fig. 1.

The bottom of the drum 5 is shown as provided with akplurality of exteriorly extending lugs or supportsl, which may-be apertured to receive the downwardly depending bolts 8, headed as at tion at various levels primary air inlets I'I. a slightly concave bottom therefor, and I9 any suitable inlet passage extending to a source of liquid fuel not herein shown. 2B is any suitable pilot baille, the details of which do not form part of the present invention.

It will be noted that the top flange I3 constitutes a complete top closure for the space between the pot I5 and the outer housing I2. 2l indicates any suitable top ring which partially restricts the open top of the pot, and which may rest on the upper edge of the pot in any suitable manner. Outwardly extending lugs 22 are spaced about the bottom of the member I2, being secured for example at the bottom I4. They are shown as outwardly extending and as havingIv Any suitable means may be employed for de,-

livering air to the space between the members I2 and I5, and for thereby delivering primary and secondary air through the inlets I1 and I 6, respectively. For illustrative purposes I show a unit which includes a motor 28 and a fan 29. It will be understood that the motor and fan deliver I air from the space within the housing I.

Referring to Figs. 4 and 5, I illustrate variant means of securing the pot unit in place. In Fig. 4, for example, I illustrate ears 1b, to which bolts 8b may be hinged. In Fig. 5 I illustrate abutment flanges lc, to which bolts 8c may be secured, as by an upper hook v.portion 8d.

^ In the use of the device, if access is desired to the pot unit, or when its removal is required, the f y operator simply opens the door 25, loosens ,ther

wing nuts I0, swings the bolts 8, 8b or 8c outwardly, and drops the entire pot unit, which can then be readily yremoved outwardly laterally through the door 25.'

It will be realized that whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape,l number and disposition of parts without-departing from the spirit of my invention. I therefore wish my description and drawing to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.

Iclaim:

1. In a floor furnace and burner therefor, an outer shell having a top aperture opening into the space to be heated, a heater drum supported on and mounted within said shell, its upper end terminating below the plane ofthe top of the outer shell, its lower end terminating substantially above the bottom of the shell, a flue for said drum extending outwardly through the side of said shell, said shell having a side access aperture adjacent the bottom thereof, and a removable closure therefor, and a burner unit including a pot and an outer housing surrounding said pot, and means for directing air into the space between said outer housing and the pot, said burner unit and air directing means being of such dimensions in relation to said access aperture as to be insertible or removed bodily therethrough, and means for removably securing said burner unit in relation to said heater drum, including manually operable connections located in horizontal alignment with said access aperture.

2. In a floor furnace and burner thereforl an outer shell having a top aperture opening into the space to be heated, a heater drum supported on and mounted within said shell, its upper end terminating below the plane of the top of the outer shell, its lower end terminating substantially above the bottom of the shell, a ue for said drum extending outwardly through the side of said shell, said shell having a side access aperture adjacent the bottom thereof, and a removable closure therefor, and a burner unit including a pot and an outer housing surrounding said pot, said burner unit being of such dimensions in relation to said access aperture as to be insertible or removed bodily therethrough, and means for removably securing said burner unit in relation to said heater drum, including manually operable connections located in horizontal alignment with said access aperture.

3. In a floor furnace and burner therefor, an outer shell having a top aperture opening into the space to be heated, a heater drum supported on and mounted within said shell, its upper end terminating below the plane of the top of the outer shell, its lower end terminating substantially above the bottom of the shell, a ue for said drum extending outwardly through the side of said shell, said shell having a side access aperture adjacent the bottom thereof, and a removable closure therefor, and a burner unit including a pot and an outer housing surrounding said pot, said burner unit being of such dimensions in relation to said access aperture as to be insertible or removed bodily therethrough, and means for removably securing said burner unit in relation to said heater drum, including one or more tension members extending downwardly from the heater drum, and movable in relation thereto when released, abutments on the outer housing about the pot, and manually operable connections between said abutments and said depending tension members located in horizontal alignment with said access aperture, the burner unit and the bottom of the heater drum being provided with opposed abutment means, whereby when the securing means have been moved to securing position, the burner unit is firmly secured to the bottom of the heater drum.
